play audio from internet using AVAudioPlayer

Question

I am implementing AVAudioPlayer to play audio and it works perfectly well while playing files locally stored in the PC.

But when i give the url of some audio file over the internet, it fails sadly. Here's what the code looks like:

NSString *url = [[NSString alloc] init];  
url = @"http://files.website.net/audio/files/audioFile.mp3";  
NSURL *fileURL = [[NSURL alloc] initWithString: url];  
AVAudioPlayer *newPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: nil];

Could anybody please point out the problem and what could be done?
Thanks!

Have you tried to provide an error object to see whether it contains an error description? — Toastor, Sep 03 '10 at 12:47
Nope, but the app doesn't crash either...just the view appears and nothing happens. — bangdel, Sep 03 '10 at 13:12

Use AVPlayer to stream audio/video based on http url's. It will work fine. AVAudioPlayer is for local files. Here's the code

NSURL *url = [NSURL URLWithString:url];    
self.avAsset = [AVURLAsset URLAssetWithURL:url options:nil];    
self.playerItem = [AVPlayerItem playerItemWithAsset:avAsset];    
self.audioPlayer = [AVPlayer playerWithPlayerItem:playerItem];    
[self.audioPlayer play];

This is what the Apple docs say:

The AVAudioPlayer class does not provide support for streaming audio based on HTTP URL's. The URL used with initWithContentsOfURL: must be a File URL (file://). That is, a local path.

I tried other method initWithData on AVAudioPlayer instead of initWithContentsOfURL. First try to get MP3 file into NSData and then play this data.

Look at my code here.

Use AVPlayer and monitor its status to start playback.

Here is a workable example, hope it would be helpful.

@implementation AudioStream

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *,id> *)change context:(void *)context
{
    if (context == PlayerStatusContext) {
        AVPlayer *thePlayer = (AVPlayer *)object;
        switch ([thePlayer status]) {
            case AVPlayerStatusReadyToPlay:
                NSLog(@"player status ready to play");
                [thePlayer play];
                break;
            case AVPlayerStatusFailed:
                NSLog(@"player status failed");
                break;
            default:
                break;
        }
        return;
    } else if (context == ItemStatusContext) {
        AVPlayerItem *thePlayerItem = (AVPlayerItem *)object;
        switch ([thePlayerItem status]) {
            case AVPlayerItemStatusReadyToPlay:
                NSLog(@"player item ready to play");
                break;
            case AVPlayerItemStatusFailed:
                NSLog(@"player item failed");
                break;
            default:
                break;
        }
        return;
    }

    [super observeValueForKeyPath:keyPath ofObject:object change:change context:context];
}

- (void)playAudioStream
{
    NSURL *audioUrl = [NSURL URLWithString:@"your_stream_url"];
    AVURLAsset *audioAsset = [AVURLAsset assetWithURL:audioUrl];
    AVPlayerItem *audioPlayerItem = [AVPlayerItem playerItemWithAsset:audioAsset];
    [audioPlayerItem addObserver:self forKeyPath:@"status" options:0 context:ItemStatusContext];
    self.player = [AVPlayer playerWithPlayerItem:audioPlayerItem];
    [self.player addObserver:self forKeyPath:@"status" options:0 context:PlayerStatusContext];
}

@end
